So I was happily enjoying fallout shelter, I had nine floors and about 60 dewellers, life was going great. I soon decided I was going to send Moria and Mr Tenpenny out into the wastes armoured to the teeth with mini guns. They survived out there for a good 2 days then I decided to send them back to the vault as their health was getting low. During the wait period I decided to buy 40 lunch box lunches but decided to open them when the explorers came back. I left the device on overnight and woke up to the notification that they had returned, eager to start cracking open some lunch boxes I started to load the game, however the game did not load, instead it just froze after the screen where you select enter vault. I don't know what to do i don't want to have to reset or that's my money down the drain ;_;
